Um, it works for me. Please share your project.

You mean, putting text in the costume? Yeah, that's on our list; it'll happen eventually. (Actually we want to invent a new Text Box object that can be used as a costume but can also be edited interactively and can be read and written by your program.) Meanwhile, two ideas: (1) Use an external editor to display the text, take a screenshot, and import it as a costume; (2) Use the LABEL block to write the text on the stage, then right-click the stage to take a picture of it for use as a costume.

PS I'm glad you like Snap!!

Thank you, can't wait to see it!

Hey, I'm new to Snap! and I need help with building an app or Windows 32-bit. See, I import the .xml file and I choose “Windows 32-bit” but when I hit “Build my app,” it takes so long my computer dies before it's done and then I have to restart. I'm using firefox. Should I try chrome instead?

Hi Puppers!

It takes Snapp! quite a while to turn a project into an app, but it usually succeeds in the end.

Can you share your project so that we can take a look?

How do you ringify hat blocks?

RealisticallyGrim

I've been having a problem with my snap project I have for school. I have a sprite that is supposed to act like a bouncing ball. and for some reason when the ball falls, it moves much slower than when it comes back up. I'm not sure why this is though. here's a link to it if you want to check it out. But yeah, can anyone explain what's up and how I might be able to fix it? Thanks so much!

You don't. What would it mean? Why do you want to do it?

Hmm, is this for the AP Create Task? I don't think we're allowed to help with that.

I want to ringify hat blocks like this

({when @greenFlag clicked::control} @addInput::grey ring)

But why? The main purpose of ringifying is to be able to use the “run” block - what does “run when green flag clicked” even mean?

AP Create Task? Sorry, no. I'm in a TEALS class.

Actually, I was able to figure it out. Though now I have a different question. does anyone know how to create a double-click joker? (click twice to trigger something.)

Use a variable, initial value False. The first click sets it to True. If clicked and already true, do the something.

Ah, this makes sense.

So

when green flag clicked

basically acts as a

wait until @greenFlag clicked ::control

is this correct?

I'm not 100% sure what you mean, but I think you could use broadcasts or custom blocks to do the same thing?

when gf clicked
broadcast [green flag clicked v]

run ({broadcast [green flag clicked v]} @addInput :: grey ring) :: control @addInput

when I receive [green flag clicked v]

It's a hat block. Nothing happens when you run it.

How does this block work?

(JavaScript function \(\ @addInput \)\ \{\ [] } ::operators)

Well, there is a text-based programming language called JavaScript, and if you want to write some code in that language instead of Snap, you can define a function and it will act like a Snap! one.

Let's do an example of a function that joins two strings together.

function (firstParameter, secondParameter) {
    return firstParameter + secondParameter;
}

is how you would write it in JavaScript. Well, you can write that using the Snap! block like so

(JavaScript function \(\ [firstParameter] [secondParameter] @addInput \)\ \{\ [return firstParameter + secondParameter;] } ::operators)

what's great about this is that you can interact with sprites, the canvas (where the result is displayed) and also some features that are only available in JavaScript (perhaps also a flaw with the block).

For example, pop-ups and playing arbitrary audio becomes much easier with the block.

But how do you run it? Well, you can just use the block just like any other reporter block in Snap!, you can call it

call (JavaScript function \(\ [firstParameter] [secondParameter] @addInput \)\ \{\ [return firstParameter + secondParameter;] } ::operators) [Hello ] [World] @addInput ::control reporter

You can use it as a mapping function over an array, and much much more.

As I say, it can also modify lots of things such as the costumes of snap, something that other blocks in Snap can't do. Good luck!
